Abstract

Provided is a photoelectric conversion device comprising an electrically conductive film, a photoelectric conversion film, and a transparent electrically conductive film, wherein the photoelectric conversion film contains a fullerene or a fullerene derivative and a photoelectric conversion material having an absorption spectrum satisfying at least either the following condition (A) or (B):λM1<λL1 and λM2<λL2  (A)λM1<λL1 and Δ|λM1−λL1|>Δ|λM2−λL2|  (B)wherein λL1, λL2, λM1 and λM2 are the wavelength at an absorption intensity of ½ of the maximum absorption intensity in the wavelength range of from 400 to 800 nm, each of λL1 and λL2 represents the wavelength in a chloroform solution spectrum when the photoelectric conversion material is dissolved in chloroform, and each of λM1 and λM2 represents the wavelength in a thin-film absorption spectrum of the photoelectric conversion material alone, provided that λL1<λL2 and λM1<λM2.
